Who is Eris and what part did she have in the Trojan War?

Eris is the Goddess of Strife and Discord. Since she is so horrible, she was the only goddess Not invited to Peleus and Thetis's wedding. She has an Apple inscribed with:" to the fairest" She went anyway and threw her Apple there in rage. 3 goddesses claimed it was theirs: Hera, Athena, and Aphrodite. They asked Zuess to judge who it belonged to, but he would take no part in it, so he sent them to Paris. They all had bribed him, Hera promised him to be ruler of Europe and Asia Minor. Athena promised to make him the greatest warrior. Aphrodite promised the most beautiful person in the world. Being young and foolish, Paris chose Aphrodite. The most beautiful person in the world was Helen of Sparta. She was married to Menelaus. Paris had to get Helen alone to make her his wife. When Menelaus was gone, Paris told Aphrodite to make Helen his. She did so. They ran away together. When Menelaus returned, he realized what happened and swore revenge. Thus began the Trojan War. Hope this helped you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
